1. Giới thiệu
Bài lab hướng dẫn cài đặt Asterisk + FreePBX + thư việ PJSIP trên Ubuntu v14
Note:
– Asterisk V12, v13
– FreePBX v12
– Ubuntu v14.04 LTS 32bit & 64 bit
– Console text mode (init 3)
2. Các bước cài đặt
Bước 1: Cài đặt các gói phụ thuộc
apt-get update && apt-get install whiptail -y && apt-get upgrade -y && apt-get dist-upgrade -y && reboot
apt-get install -y build-essential autoconf automake curl lua5.1 linux-headers-generic libncurses-dev zlib1g-dev libssl-dev libxml2-dev libsqlite3-dev uuid-dev libspeex-dev libspeexdsp-dev libogg-dev libvorbis-dev libasound2-dev portaudio19-dev libcurl4-gnutls-dev libpq-dev unixodbc-dev libsqlite3-dev libmysqlclient-dev libneon27-dev libgmime-2.6-dev libusb-dev liblua5.1-0-dev libgtk2.0-dev libmysqlclient-dev libbluetooth-dev libradiusclient-ng-dev freetds-dev libsnmp-dev libiksemel-dev libcorosync-dev libnewt-dev libpopt-dev libical-dev libspandsp-dev libjack-dev libresample-dev libc-client-dev binutils-dev libsrtp-dev libgsm1-dev libedit-dev libjansson-dev libldap-dev libxslt1-dev libmyodbc doxygen subversion git mpg123 e2fsprogs php5 php5-curl sqlite3 uuid php5-cli php5-mysql php5-gd php-pear sox bison flex tftpd mailutils nano ntp apache2 mysql-client mysql-server postfix sudo xmlstarlet
Note:
– Đặt password mysql root khi được hỏi trong quá trình cài đặt.
– Thiết lập timezone: dpkg-reconfigure tzdata
Bước 2: Download and install source files
DAHDI
Cài đặt DAHDI khi sử dụng máy chủ vật lý và sử dụng telecom card
cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz
tar zxvf dahdi-linux-complete*
cd /usr/src/dahdi-linux-complete*/
make && make install && make config
service dahdi start
PJSIP
cd /usr/src
wget http://www.pjsip.org/release/2.5.5/pjproject-2.5.5.tar.bz2
tar -xjvf pjproject*
cd /usr/src/pjproject*/
./configure –prefix=/usr –enable-shared –disable-sound –disable-resample \
–disable-video –disable-opencore-amr CFLAGS=’-O2 -DNDEBUG’
make uninstall && make dep && make && make install && ldconfig
Kiểm tra pjsip: sử dụng lệnh ldconfig -p | grep pj, nếu thấy xuất hiện một vài link *.so trong /usr/lib/ –> Cài đặt PJSIP thành công.
ASTERISK
cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-13-current.tar.gz
tar zxvf asterisk-13-current.tar.gz
cd /usr/src/asterisk-13*/
make distclean
./configure
Nếu ./configure bị lỗi với cannot find ptlib-config, sử dụng ./configure –without-pwlib chỉ cần khi sử dụng H323
cd /usr/src/asterisk-13*/
make menuselect.makeopts
#To select compile options manually run make menuselect instead of the following command
#To list command line options run menuselect/menuselect –list-options
#If Asterisk fails to run on a virtual machine try add “–disable BUILD_NATIVE”
#To add asterisk realtime for applications such as A2billing add “–enable res_config_mysql”
menuselect/menuselect –enable cdr_mysql –enable EXTRA-SOUNDS-EN-GSM menuselect.makeopts
Create Asterisk user, compile, install, and set ownership.
adduser asterisk –disabled-password –no-create-home –home /var/lib/asterisk –shell \
/sbin/nologin –gecos “Asterisk User”
make && make install && chown -R asterisk. /var/lib/asterisk
Freepbx GUI
pear install db-1.7.14
If the DB fails to install try gunzip /build/buildd/php5-5.5.9+dfsg/pear-build-download/*.tgz followed by pear upgrade /build/buildd/php5-5.5.9+dfsg/pear-build-download/*.tar
VERSION=12.0
USERNAME=asteriskuser
PASSWORD=amp109
#The following commands must be entered one at a time in order to enter the mysql root password
mysqladmin -p create asterisk
mysqladmin -p create asteriskcdrdb
mysql -p -e “GRANT ALL PRIVILEGES ON asterisk.* TO $USERNAME@localhost IDENTIFIED BY ‘$PASSWORD’;”
mysql -p -e “GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO $USERNAME@localhost IDENTIFIED BY ‘$PASSWORD’;”
mysql -p -e “flush privileges;”
cd /usr/src
git clone -b release/$VERSION https://github.com/FreePBX/framework.git freepbx
cd /usr/src/freepbx
./start_asterisk start
mv /var/www/html /var/www/html_orig
./install_amp –installdb –skip-module-install –username $USERNAME –password $PASSWORD
#Press ENTER for all the questions including the incorrect IP address.
Do not be concerned by the warning messages.
# Minimal module install
amportal a ma upgrade framework

amportal a ma installall
touch /etc/asterisk/manager_additional.conf
touch /etc/asterisk/manager_custom.conf

amportal chown
If the GUI complains about the framework module or a missing /usr/sbin/amportal file try amportal a ma delete framework followed by amportal a ma upgrade framework.
Post-install tasks
Change the webserver run user and group name to asterisk.
sed -i ‘s/\(APACHE_RUN_USER=\)\(.*\)/\1asterisk/g’ /etc/apache2/envvars
sed -i ‘s/\(APACHE_RUN_GROUP=\)\(.*\)/\1asterisk/g’ /etc/apache2/envvars
chown asterisk. /var/lock/apache2
service apache2 restart
Enable .htaccess files to protect sensitive webserver directories.
nano +13 /etc/apache2/sites-enabled/000-default.conf
# Add this underneath the DocumentRoot /var/www/html line
<Directory “/var/www/html”>
AllowOverride All
</Directory>
Change default “upload_max_filesize” to 20M to allow larger music on hold files.
sed -i ‘s/upload_max_filesize = .*/upload_max_filesize = 20M/’ /etc/php5/apache2/php.ini
Set Freepbx to start on boot.
nano /etc/rc.local
Add
/usr/local/sbin/amportal start
Before exit 0
reboot
Optional
Log File Rotation
If this is not done the log files will keep growing indefinitely.
nano /etc/logrotate.d/asterisk
/var/log/asterisk/queue_log
/var/spool/mail/asterisk
/var/log/asterisk/freepbx_debug.log
/var/log/asterisk/messages
/var/log/asterisk/event_log
/var/log/asterisk/full
/var/log/asterisk/dtmf
/var/log/asterisk/fail2ban {

create 0640 asterisk asterisk
postrotate
/usr/sbin/asterisk -rx ‘logger reload’ > /dev/null 2> /dev/null || true
endscript
}
TFTP
If you plan to use hardware SIP phones you will probably want to enable the tftp server.
nano /etc/xinetd.d/tftp
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /tftpboot
disable = no
}
Now make the directory and restart the daemon to start tftp.
mkdir /tftpboot
chmod 777 /tftpboot
service xinetd restart
Digum addons
This is used to register digium licenses.
cd /usr/src
wget http://downloads.digium.com/pub/register/linux/register
chmod +x register
./register
To install the individual addons refer to the README files and ignore the register instructions.
